means for making a quick adjustment of the channeling tool from one side of the track tothe other so that a plurality of par-" V allel grooves'may becut'without shifting the traclrway.

The trackwayzfor a channelingmachine is customarily formed of connected sections composed each of parallel united rails, the

sections-beinglaid to form a continuous straight trackway andibrought to a level or into alinement by means of blocksv placed beneath the rails.

The laborv of shifting such a trackway and adju'sti-ngit to. a new position forms a very large proportion of the :laborinvolved in the channeling operation. This is:espe.- cially the-case with modern high powered channeling machines where the machines,

and consequently the trackway, are very heavy and cumbersome, and is alsosespecizrl ly the case in channeling relatively soft stone, where the. cut" is quickly made, while. the shifting of thetrackway requires the same amount of time and labor.

The object of the present invention is to provide means whereby the channeling tool may be easily and'expeditiously reversed in its relation-to the trackway so that after completing a channel groove "at onezside o-f the'trackway, it may be *causedat will to overhang the opposite sideiof thetrackvvay and cut a second parallel channel groove thereat. The number of times the trackway must be shifted, blocked up, andp'laced in .alinement is thereby reduced one-half, it

being-necessaryto move the trackway once ous ways, but, as disclosed in the illustrative embodiment. herein described, the reversal of the channelingtool is-obtained-by pro-.

viding a turntable on the truck of the channeling machine, which turntable carries the channeling devices and preferably, though driving devices. The turntable may be quickly [turned to cause the tool to overhang either side of the truck and to cut a groove at either side of the trackway.

not necessarily, the tool feeding'andtruck The. invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out inthe appended claims.

In the drawings, Figure 1 shows, partly in end elevation and partly in section, on the line 1-' l, Fig. with certainzparts removed, a channeling machine einbodying one form of the inven- Fig. 1.

Referring to the drawings and to the embodiment of the inventionthere submitted for illustrative purposes, I have .shown a track channeler carrying the'usual gang 4: of channeling tools mounted upon the truck wheels 5, the latter adapted to move along the usual rails 6, which are customarily united into connectedrsections' to form a portable trackway laid along the quarry bottom. Herein the truck wheels are mounted upon axles 7 which carry themain truck a support 8v constituting a member having a fixed relation to opposite sides of the trackway. That is to say, although; the relation of the tool gang and tool actuating parts to be described is reversed with reference to the trackway in cutting a second or parallel an intermediate reversible support in the form of a turntable or rotatable platform'9'. The turntable is in the form of a rectangular frame having a cylindrical, central depres-' sion 10' which is located within a similar rammes centrally depressed part 11 of the truck frame. The main truck portion is also in the form of a rectangular frame carrying the two axles with their four Wheels, each aXle being provided with aworm gear 12,,-

preferably located in a central longitudinal plane, a 6., substantiallymidway between the rails. V

The upper platform or turntable is adapted to rest upon a finished ring or sun-.-

face 13 presented by the truck frame, and is centered to turn about a central axis by means of segmental projections 14 which constitute side bearings and engage the walls of the cylindrical depression 10 on the turntable.

' This arrangement provides that the platform can be reversed by merely reversing the turntable and bringing all the operative 'parts'of the channeler into the same relation to-one side'of the trackway' which'th'e'y previously bore to the opposite side thereof.

7 Any suitable means for propelling the channeler may be employed, but herein each 'wormgear 12 is adapted to be engaged by one of two worms 15 mounted upon the worm shaft 16, the latterbeing driven from any suitable motor, such as the upright truck. driving motor 17, through appropriate transmission gearing. Herein the engine 17 has the drive shaft 18 which turns the two bevel gears 19 and 20 on the'countersh'aft 21 the actuating lever 25, are employed to 'clutch'either beveled gear at will to the in opposite directions by means of the bevel driving pinion 18.

construction, moved by the slide rod 24 and countershaft 21. The latter carries the driving gear 27 which meshes with the driven gear 28 the latter secured to the worm shaft 16. By this means the Worm shaft may be connected to'bedriven by either driving gear 19 or 20, While theremaining gear is disconnected, or both gears may be disconnected, whereby the truck may be driven in one direction or the'other or held at rest. The worms 15 are carried in boxes Q journaled near the top of the standard 732.

This is adapted to turn the usual feed screw r 28 (see Fig. 2') the under sides of-which are open so that when the turntable is turned through 1809 one worm may be withdrawn from its gear and swung into mesh with the oppos te gear, and the remaining worm s1- multaneously brought into engagement with 7 the first gear.

Preferably the toolfeeding mechanism is also carried 'upon the turntable. For this purpose the tool feed driving chain 29 is employed, driven from the sprocket wheel 30 and adapted to turn-the transverse shaft 31 83 through the bevel gears 34 so as to advance the sliding frame 35 which carries the tool actuating engine and the crosshead ing the sprocket wheel 30 for the tool feed,

Clutch devices 22 and- 23 of well known guides 36 on the standard guideways' 37.' i

The standard is adjustably supported at the side of the truck upon the trunnion shaft 32 extending lengthwise the truck. V l

, Referring now to the mechanism fordrivan upright support 44 for'the drive shaft 38' '43 bolted to the turntable and also provides V and the countershaft 21.- For turning the driving sleeve 41 in either direction at will, thereby to raise or lower the tools, the sleeve is provided at opposite ends Withthe clutch devices 45 and 46; By means of the actuatmounted on the wormshaft 16 and mesh ingrod47 and lever 48 these may be used V to clutch the drive sleeve 41 to or unclutch the same from the oppositely driven gears 49 -andi50, which latter are 'rotatably.

with gears 51 and 52 connected respectively to or formed integral with thebevel gears19 and 20 on the countershaft 21. By throw ing the actuating lever 48, the driving sleeve;

7 41may be clutched to either gear 49. or 50 at will for raising or lowering the tool, ormayf;

be unclutched from both gears to leave the tool fixed, and these conditions may be had irrespectiveof the direction of travel of the' truck. I

pressed part 11 of the truck frame 8 isprolvidedwith an internal annular rack 53 which is engaged by a pinion 54 fast upon an upright shaft 55- journaled in a bearing 56 carried by the cylindrical portion 10 of the turntable, the latter being provided with a pinion 54 and permit the same to engage the a rack 53. Keyed or otherwise secured to the suitably disposed opening 57 to receive the '7 shaft55 is a worm gear 58 which meshes I with a worm' 59' on a sleeve 60 having a r splined connection with the countershaft 21,

whereby said sleeve and Worm are caused-to rotate with said shaft but arepermitted longitudinalvmovement thereon, the eXten-tof said movement being limited by collars or I equivalent stops 61 and. 62 which are en 7 gaged by opposite ends respectivelyof said sleeve 60. Said collars or stops are so positioned that when the sleeve 60 engages the gages the stop 62 said worm and worm gear rotated in one direction (theparts beingin the position shown in Fig. 3), the sleeve 60 is held; against longitudinal movement by engagement of the left end thereof With the collar-61 the worm 59 is in engagementwith f I the w0r1n-gear58, and when said sleeve 'cn-Q V V are out of engagement.
